Does Sysview Performance Management use PSASTAK?

Products

• SYSVIEW Performance Management

Issue/Introduction

We are applying z/OS 2.3 UA96475 Meltdown Vulnerability and I need to know if SYSVIEW Performance Management uses IHAPSA field PSASTAK. 

Software must no longer reference the IHAPSA field PSASTAK. 
With this PTF, PSASTAK is no longer the beginning of the normal FRR stack.
PSACSTK is an existing pointer to the beginning of the normal FRR stack. 

Software that references PSASTAK must be converted to use PSACSTK as the pointer to the normal FRR stack.

Environment

SYSVIEW All releases with z/OS 2.3 @UA96475 or later

Resolution

The SYSVIEW product does not use IHAPSA field PSASTAK.
